HazMat Fee

An item is classified as a dangerous good if our website displays Hazardous Material (HazMat) information for it. There is a HazMat shipping fee for each item that qualifies as a dangerous good, except in the following scenarios:

The shipment is processed through FedEx Ground under the Limited Quantity option.

Each bottle is packed as an Excepted Quantity, with a maximum of 1g for items in class 6.1 packing group I or II, and up to 25g for all other hazardous materials.

If shipping is charged to your FedEx account, the HazMat fee will be billed directly by the courier. Otherwise, the fee will be included on your invoice. To help you avoid the HazMat fee, we can package a 5g order of a class 6.1 packing group I or II material as five separate 1g units, and a 100g order of any other dangerous good as four 25g units. This packaging adjustment will be made unless you instruct otherwise on your purchase order. Below, you will find the fee schedule from FedEx for handling hazardous materials.

Description

This boronate-functionalized pyrazole integrates readily into Suzuki-Miyaura cross-coupling reactions under standard conditions. The tetramethyl-dioxaborolane moiety provides exceptional stability and moisture tolerance, enabling reliable use in diverse synthetic workflows.

Application

3-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole serves as a stable, bench-ready boronate building block for Suzuki-Miyaura cross-coupling reactions. Its pyrazole core provides orthogonal reactivity and enhanced solubility, enabling efficient incorporation into heterocyclic scaffolds. The tetramethyl-substituted dioxaborolane moiety ensures high functional group tolerance and minimal protodeboronation, facilitating reliable coupling with aryl, vinyl, and heteroaryl halides under standard catalytic conditions.
